Climate is a descriptor used by the IISS to denote average planetary temperate ranges.

Description (Specifications)[edit]

Climate and weather are fantastically complicated things affected by dozens upon dozens of factors. With a few exceptions due to fantastically exotic conditions, most planets have a wide variety of climates, biomes, microclimates, ecological zones, and environments. The single-biome world is, for the most part, a very rare fantasy.

  • Climatological trade codes represent an equatorial mean climate band average reading.
  • Example: For Earth, this is 22. On Earth, with an axial tilt of 23 degrees, the Climate at season height sometimes ranges from minus -73 to 46, and the overall mean temperature is 16. Earth's hottest temperature has been recorded at 70 and coldest at -89.
  • Smaller worlds will have less variation. Faster rotation will have less variation. Lower axial tilt will have greater variation at any time of the day, but less variation on any given day (that is, the poles will not get as cold relative to the equator).

T5SS Climate Categories Table[edit]

The descriptors are as follows:
